This invention relates to atire removing tool and itis one'object of the invention to provide a tool by means or which large tires; such as used upon trucks and buses may be easily broken loose from a wheel rim and removed-therefrom.

4 Another object of l the invention --toprovide a tool so constructed that when-fit lS- HL use a lever carrying jaws at one end. may: have its jaws applied to a side flange of the rim,=a second lever carrying arms at oneend moved to bring its arms into position for pressing engagement with the outer side of the heel of the tire casing, and. al jchird lever to which-the second lever is pivoted when swung about its pivoted connection with the first leverand apply pressure, to the second lever and causethe'tir'e casing 'td'be 'forced'off of the wheel rim.

Another object of the invention is to'provide a tool which is of light weight, very strong, and

capable-of easily dislodging a large tire from the rim orawheel. nnother' object-of-the invention is to provide a tire removing tool whichis of simple construction, easy tooperate, and'capable 'of being manufactured at smallcost... p

The invention is illustrated in the accompanying drawings wherein: j; "-Fig;l is a view showing-the tire-removing tool in side elevation and applied to a wheel rim shown in section for removing the tire from the rim.

Fig. 2 is a view similar to Figure 1 showing the tire-engaging arms of the tool moved into position for pressing engagement with the tire.

Fig. 3 shows the long pressure-applying lever of the tool swung to a position for applying pressure to the tire-engaging arms.

Fig. 4 is a view looking at the front or inner end of the tool, the view being along line 4--4 of .Figure 1. I Fig. 5 is a view taken along the line 5-5 of and 4 spaced from each other to provide a recess 5 into which the flange 6 of a wheel rim fits when the tool is applied to the rim for removing a tire 8. Since the bill or hook 4 is curved longitudinally the lever I may have its head 2 applied to the flange of the wheel rim, as shown in Figure 1,

and the leverthen-tiltedfrom the inwardly 111-! clined positionshown therein-to the outwardly inclined position of Figure 2-and thebill 4 will then en'gage'under the flange 6 and cause the lever to be supported-in theoutw'ardly inclined position l r i 1 I I.

A relatively long lever 9 is formed from a strip of strong metal; 1 This metal strip'is bent'midway its length to form a handle-10 of double thick ness and arms which are spaced from each othera suflicientdistance to straddle thehead 2 of leverand at their front ends the arms are formed withheads 12 which are substantially triangular inorder to provide portions which project from the arms II and are pivotally mounted at opposite sides of the head 2 by a pin l3. openings 14 are formed through the heads iZ-to receive pintles I5 projecting inwardly from inner endsof arms [6. These arms 16 are curved longitudinallyand have their free ends flattened to' form. feet I! for engaging ibetweentheflange 610i: thetrim and'the confronting bead of the tire flandtallow pushing force to be exerted without cutting the tire. The armslfi are..operated by a lever I8 formed froma bar of strong metal, and this. lever 'hasits inner or front end bent toaform a side arm: [9 extending between and vwelded to theiarms I6. Since the side arm .extendsacross the leverl the lever -l8 may-be swung about; the pintles l5 as pivots and move the arms l6 from the raised position shown in Figure 1 to the lowered position shown in Figure 2, and since the arms ll of the lever 9 are longer than the lever I this lever 9 may be swung about the pin from the position shown in Figure '1 to that shown in Figure 3. When the improved tire removing tool is in use it is applied to the rim of a wheel as shown in Figure 1, the wheel being placed flat upon the ground and the flange 6 of the rim being engaged in the recess 5 of the head 2 of lever I. The lever I is then swung to the position shown in Figure 2 and as its hill 4 moves under the flange of the rim a portion of the heel of the tire 8 will be forced away from the flange and since the lever I will be tilted outwardly of the wheel rim and the bills or hooks engaged with side faces of the flange 6 the lever I will be supported in the position shown in Figure 2. After lever I has been swung to the outwardly inclined position a foot is placed upon lever 9 to hold it in a substantially horizontal position diametrically across the wheel rim and the lever. l8 grasped and swung from the position shown in Figure 1 to that shown in Figure 2. As the lever it is swung upwardl and outwardly and then downwardly to the position in which it extends radially from the rim at a side of the tire 8 the arms I6 will be swung downwardly against the confronting side wall of the tire and into space between the flange 6 of the rim and the confronting head of the tire. Pressure will thus be exerted upon the tire to break its bead loose from the tire rim and force this bead away from the flange 6 and partially across the rim. A foot is then placed upon the lever; to hold it in the position shown in FigureZ and the handle In of lever'9 grasped and pull exerted to swing this lever upwardly and outwardly and then downwardly to the position shown in Figure 3 where it projects radially from the rim and angularly from the lever I. In view of the fact that the pintle l5 move in a circular path about pin l3 from the position shown'in Figure 2 to the lowered position shown in Figure 3 the arms IE will be shifted downwardly and their wide and flattened feet I! will exert pushing pressure against the-tire across the wheel rim anddislodge the tire from the rim to such an--extent that the :tire maybeeasily removed from the rim, a puncture repaired-and the tire replaced, or anew tirelapplied to the rim- Having thus described the invention, what is claimed is:

-l. A tire removing tool comprising a lever having a head at its front end formed with flat side faces and at its front end having a lug and a longitudinally curved bill defining arecess betweenthe bill and the lug for receiving a side flange 'of' a wheel rim and mounting the lever upon the flange for tilting movementtransversely of the wheel rim, a second lever having a handle and arms extending therefrom and 1 terminating inheads at their front ends-disposed at opposite sides of the head of the first lever, a pin passingthrough the heads of the levers and pivotally mounting the second lever for swinging movementfrom a position in which it extends di= ametrically, across a, rim to a position in which it'zprojects outwardly from the rim at a side of a tire mounted upon the rim, longitudinally curved: arms having outer ends formed with feet forxengaging between the rim flange andthe-com frontingcbead of a tire on the rim, said curved armshaving inner 'end's formed with pintles pro-' jecting from their inner sides and rotatably ening a side flange of a wheel rim and tiltably mounting the lever in an upright position upon the, flange said-lever having a member for engaging between the flange and a bead of a tire astheleVeris swung from its initial position, a second'lever pivoted at its front end to the front end of the first lever for swinging movement from a positionover a rim diametrically thereof to a position extending outwardly from the rim radially thereofat. a side?of ajtirecarriedbythe rim-,1 and -a third --lever--'having-; atwoneendyarms extending; forwardly: and rearwardly therefrom and having their rear endspivoted to-the front end of thesecond lever in eccentric relationto the pivot which-joins the;first'and second levers and their front ends--formed :Wil3hfeet -for engaging between the fiangetof 'the rim and -the bead ---of the tires to lac-removed. g a HIRAM E.
